Incazelo Yomkhiqizo

I-Anhydrous Borax ibizwa nangokuthi i-sodium tetraborate, i-alpha orthorhombic crystal melting point 742.5℃,

Ukuminyana 2.28g/cm3, β orthorhombic crystal point melting point 664℃. Ukuminyana okungu-2.75, ukubukeka kuyikristalu emhlophe

noma i-crystal efana nengilazi engenambala, i-hygroscopicity eqinile, encibilika emanzini, i-Glycerin incibilika kancane ku-methanol ukuze yakhe isixazululo ngokugxila kuka-13-16%. Isixazululo saso esinamanzi sine-alkaline ebuthakathaka futhi asincibiliki otshwaleni.

I-Anhydrous Borax iwuketshezi olungenamanzi olutholakala lapho i-borax ishiselwa ibe ngu-350 ~ 400℃, Uma ibekwe emoyeni, Ingakwazi ukumunca umswakama futhi ibe yi-borax decahydtate noma i-borax pentahydrate.

QAPHELA: I-Borax iyikristalu ezinzile ngaphansi kwezimo ezijwayelekile zokugcinwa futhi ngeke isabele ngamakhemikhali, kodwa uma ithola

imanzi, izokhulula umkhondo wokushisa ngamanzi ukuze ikhiqize i-borax decahydrate, ngakho-ke idinga ukugcinwa kahle futhi ingavezwa kumswakama noma izinga lokushisa, endaweni eshintshayo, ngaphandle kwalokho izoba agglomerate. Ngakho-ke, kuyadingeka ukuqinisekisa ukupakishwa okuhle.

Isicelo

1. Ezinye izici ze-borax engasebenzi kahle zifana ne-borax

2. I-anhydrous borax isetshenziselwa ingilazi yekhwalithi ephezulu, i-glaze, i-Welding flux, izinsimbi ezingenayo insimbi kanye ne-alloy fluxes, njll...

3. I-anhydrous borax iwumthombo oyisisekelo wokulungisa izinhlanganisela ezine-boron. Cishe zonke izinhlanganisela eziqukethe i-boron zingenziwa nge-borax.
